Please help and show work. I keep getting the wrong answers for these problems 1. Cell membranes contain channels that allow Na + ions to rush in. Consider a channel that has a diameter of 2.91 nm and a length of 13.5 nm. If the channel has a resistance of 18.5 GΩ, what is the resistivity ? of the solution in the channel? 2. What is the resistance of a 54.154.1-m-long aluminum wire that has a diameter of 8.79 mm8.79...

Let’s consider an electrical current through a single ion channel, as shown in the following figure. We start by treating an ion channel as a cylindrical pore through the cell membrane. The channel is of length L ≈ 5 nm and is filled with water. The concentration difference of Na+ ions across the channel is Δc ≈ 100 mM. This concentration difference produces a flux of ions through the channel given by DΔc/L, where D is the diffusion constant for...
